Description

The invention relates to a projectile with reduced penetration capability comprising a projectile jacket and a projectile core, wherein the projectile core can shatter when hitting a target, as the generically from the DE 102 39 910 A1 is known.

In the field of shooting, hunting and shooting training in the military, police and security services, it is desirable in some situations for a projectile to reduce the risks of rebounding bullets and to reduce the impact of the bullet holes of shooting ranges upon impact quickly disassembled to the target or on a bullet behind the target. It should deliver its kinetic energy as quickly as possible and at the same time have only a low penetration capacity.

For example, to reduce the impact of ball catch on shooting ranges, projectiles are used which are fired at reduced speeds and are easily disassembled. In hunting, it is necessary to reduce the risk of presence of persons, valuables, grazing livestock or hunting dogs emanating from bullets passing through the target, in particular when hunting sick animals or when using the firearm after game accidents. At the same time, however, a sufficient effect of the bullet in the target should be ensured.

Projectiles, especially for hunting, are known in a wealth of constructions. Most of these projectiles are deformed and / or disassembled when hitting a target in order to create a larger projectile cross-section in the target or to achieve a stronger target ballistic effect by the splintering effect. A controlled deformation or disassembly of projectiles for hunting is achieved by the combination of different materials, their arrangement and dimensioning each other and for example by the introduction of predetermined breaking point or lines of weakness in the projectile. Hunting projectiles should have sufficient penetration capacity to allow passage through the target at distances of 100 meters or more. A potential hazard from bullet scraps that hit the target is therefore always given.

From the US 7,966,937 B1 For example, a bullet is known which has a bullet core with a channel in which a fluid with non-Newtonian properties is present in order to achieve and control its ability to penetrate (penetrate) into a target. The fluid can be dilatant, ie, its viscosity increases when shear forces occur in the fluid. The fluid may also be rheopectic, ie its viscosity increases as a function of shear forces occurring and the time of occurrence of these shear forces. Depending on the resistance offered by a target, the viscosity of the fluid increases more or less, whereby a dynamic adaptation of the penetration capacity of the projectile to the target resistance is achieved. Deformation behavior is also controlled by the shape and cross-section of the channel. A disadvantage of this construction is that a high penetration capacity of the projectile is maintained.

Another approach is in the DE 102 39 910 A1 described. A bullet casing surrounds a projectile core, which consists of spheroidally pressed spheres or granules of a metallic material. In addition, weak lines are present in the projectile jacket, which should allow a tearing of the projectile shell on impact of the projectile on a target. Due to the target resistance of the bullet core to splinter to reach a high energy output in the target. Due to a possible incomplete splintering of the projectile core as well as possible larger splinters of the solid material of the bullet core, there is still a danger due to rebounds and splinters that penetrate the target. It is also disadvantageous that the disclosed combination of a bullet jacket with a bullet core made of a solid and compressed material requires a considerable minimum impact velocity in order to actually shatter and release the kinetic energy of the projectile.

The invention is based on the object to propose a projectile that quickly and reliably emits its kinetic energy when hitting a target and has a low penetration capacity.

The object is achieved with a projectile comprising a projectile casing and a projectile core at least partially surrounded by the projectile casing, wherein the projectile casing has lines of weakness along which the projectile casing tears open on a target starting with a minimum impinging energy of the projectile and the projectile core of at least one Material is that can split when hitting the target and is released by tearing the bullet jacket in an environment of the projectile. A projectile according to the invention is characterized in that the projectile core contains at least one fluid with non-Newtonian properties, the viscosity of which increases as a result of shearing forces in the at least one fluid, and in which the at least one fluid shatters into fragments upon sudden impact and overshoot of a shear stress limit as a result of the sudden stress. In addition, the viscosity of the at least one fluid decreases again when the limit falls below the limit value. In addition, in the fluid packing are incorporated. The fluid surrounds these fillers and fills existing spaces between the bodies. As a result of the tearing open of the projectile shell, the fluid and the packing exit from the projectile as target ballistically effective mass.

The essence of the invention is that a fluid with non-Newtonian properties (hereinafter referred to as fluid) is present and surrounds the embedded packing as a matrix. Upon impact, the projectile core splits very quickly and easily, so that the kinetic energy of the projectile is easily released and the bullet of the invention has a reduced penetration capacity.

Upon impact of the projectile of the invention with a minimum impact energy on a target, the viscosity of the fluid increases sharply and the highly viscous fluid can shatter. In the process, the fillers are also released. The fillers preferably have a small size of, for example, 0.1 to 2 mm. A small size of the packing advantageously allows a dense packing of the packing in the projectile according to the invention. The remaining gaps are filled by the fluid. The thus formed bullet core therefore preferably has no cavities. For larger caliber projectiles, the fillers may also have sizes or diameters of, for example, 5 to 50 mm.

If a material of high (> 7 g / cm ³ ) density is used for the fillers, a bullet is created which has a high weight. For example, be used as a material of the filler, for example, metal, metal alloys, ceramics or composites.

Cheap materials are iron, iron alloys, steel, copper, copper alloys, bronze, brass, zinc, tin and their alloys or lead. It can also be used filler of different materials in only one bullet core.

When using metal or a metal alloy, a high bullet weight can be achieved, which allows favorable ballistic values of the projectile according to the invention. Thus, in an advantageous embodiment, a bullet core may be formed by filler of lead. The spaces are filled with the fluid. Such a combination advantageously allows the favorable ballistic properties of lead as a material of the bullet core to be associated with a reduced penetration capacity.

In order to avoid contamination of the target with lead, the filler can, for example, be made of steel.

It is favorable if the filling bodies are stored and / or shaped in such a way that fluid is introduced between the filling bodies. This advantageously promotes splintering of the projectile core along the packing. A formation of disadvantageous agglomerates or lumps of packing is avoided.

The fillers may, for example, be spherical, oval, star-shaped or irregularly shaped. Preferred is a regular shape of the packing to achieve a defined, with respect to a longitudinal axis of the projectile rotationally symmetrical, packing of the packing and thus a predictable ballistic behavior of the projectile.

The fluid surrounds the packing like a matrix. For strong accelerations, z. B. when shooting or striking the bullet on a target, the viscosity of the fluid increases massively, the fluid is solid. During firing of the projectile according to the invention packing and fluid are surrounded by the projectile shell. An escape of the packing or the fluid is prevented. The bullet core behaves as a solid body due to the solidified fluid, whereby a twisting motion of the projectile through the bullet core is performed.

When hitting a target the bullet jacket ruptures. The fluid becomes solid and splintered, releasing fragments of the fluid and the packing. These are slightly slowed down individually at the finish. The bullet jacket receives by tearing an enlarged cross-section. Since the projectile core is not firmly connected to the projectile jacket, only a relatively low weight is brought into the target through the projectile jacket. The bullet jacket is decelerated quickly without penetrating deep into the target.

In contrast to the prior art, for example for US 7,966,937 B1 , The decrease in the viscosity of the fluid in the projectile according to the invention plays only a minor role. Upon impact and the associated abrupt increase in the rate of shear forces occurring, the viscosity of the fluid increases sharply. A rapid decrease in viscosity with a comparatively slow deceleration of the splinters of the fluid is sufficient to the penetration capacity of the To reduce splinters of the fluid. If almost no decrease in the viscosity takes place in very short periods of time, the penetration capacity is already advantageously reduced by dividing the bullet mass onto the bullet jacket and onto a number of chips of the fluid and the random packings.

A target ballistically effective mass is understood to mean that the mass achieves a significant effect in the target. Due to the target ballistic effective mass, preferably at least 25% of the kinetic energy of the projectile is transferred to the target after the impact of the projectile on a target. The target must provide the projectile with a resistance that will cause the minimum impact energy at a given minimum floor speed.

The goal is a solid or fluid body on which the projectile strikes. The body of a game or other animal is understood in this description as a solid body.

A minimum impact energy is the energy needed to cause the bullet jacket to rupture. Resistance of the target to an impacting bullet will cause the minimum impact energy. If a bullet penetrates a low resistance body, such as a paper or thin paperboard target, the projectile does have projectile energy, but the minimum impact energy is not achieved because of insufficient target resistance, i. h this does not affect the bullet. If, for example, the bullet strikes a bullet trap behind the target after striking the target, the minimum impact energy is generated when the bullet hits the bullet trap. The bullet trap is then the target in the sense of the description.

In order to provide this target ballistically effective mass, at least half of the volume of the projectile core is preferably filled by the fluid and the fillers.

The required minimum impact energy is constructionally adjustable by the choice of the materials of the bullet jacket and the course, the number and the dimensioning of the weakening lines of the projectile.

In a possible embodiment of the projectile according to the invention, the material thicknesses and lines of weakness can be chosen so that the minimum impact energy required for tearing the bullet jacket is set so low that rupture of the bullet jacket already upon impact with a little massive target, z. As a target occurs. The fluid and the packing can in this case already escape before, for example, an existing behind the target ball catch is reached, then hit the projectile only with reduced bullet weight and reduced projectile velocity.

Weak lines in this description are understood to mean all constructive and material-technical influences on the strength of the projectile casing along a line-like region of the projectile casing. Weakening lines can be introduced, for example, by material removal (for example, cutting processes, laser ablation) or material changes (for example local structural changes due to energy input by means of laser or other electromagnetic radiation) into the projectile jacket. Weakening lines can also be created in the production of the bullet jacket by different wall thicknesses of the bullet jacket. Combinations of the aforementioned influences are possible.

It is particularly advantageous when used on in-field shooting equipment that the projectile according to the invention can be completely lead-free. Even with other shooting ranges, the disposal of not contaminated with lead ball catch is simplified. In addition, no lead-containing vapors or lead-containing abrasion occur.

The bullet jacket is preferably made of a lead-free material such as copper, copper alloys, clad steel, polymer-coated copper, polymer-coated copper alloys, polymer-coated steel, tin-zinc alloys, plastic (for example, PET, PP) or a composite material. The bullet jacket may be coated to reduce drag in the barrel and to minimize wear on the barrel inner wall.

As material for the bullet core substances or mixtures are used, which behave rheopectic. For example, the fluid may be formed from polydimethylsiloxane and borate. The limit above which the fluid splits depends on the fluid used.

The projectile according to the invention may be spherical and, for example, for firing from purely mechanically acting devices such. B. be suitable from catapults. It is also possible to use the bullet to shoot from muzzle-loading weapons.

In an embodiment suitable for use, in particular as a rifle bullet, the projectile has a longitudinal axis. The projectile has a projectile head along the longitudinal axis, a floor centerpiece and a bullet tail. At least two lines of weakness extending in the direction of the longitudinal axis are present in the projectile casing in the region of the projectile head, so that at least two projectile casing strips are formed during the tearing of the projectile casing. There may also be three, four or more lines of weakness. Preferably, the lines of weakness are offset from each other by equal angles about the longitudinal axis. It can be provided that one or more of the projectile coat flags break off during a continuous penetration of the projectile.

However, it is preferred if a connection region is formed by the projectile jacket in the region of the projectile tail, in which no lines of weakness are present and through which all areas of the projectile jacket traversed by lines of weakness are connected to each other, so that the areas traversed by lines of weakness and the connection region after the Tearing the bullet jacket remain connected.

The connection region preferably has a wall thickness which is greater than a wall thickness of the shell shell in the remaining regions of the shell shell.

In this embodiment of the projectile according to the invention is a favorable material for the bullet jacket copper or a copper alloy. The toughness of these materials supports the formation of bullet jacket flags and allows the bullet jacket flags to remain in place at the joint area.

By such a design are after the impact of the projectile on the target two essential components of the projectile: the projectile core and the projectile shell, which has a greatly enlarged, preferably at least doubled by the formation of bullet jacket flags and their whereabouts at the connection region.

The bullet may have further components in addition to the bullet jacket and the bullet core in other versions. For example, a means for stabilizing the projectile during the flight may be present at the projectile.

A use of the projectile according to the invention is given, for example, for the hunting shot. When a shot on fortified, stronger to strong game, for example wild boar from about 25-30 kg body mass, an impact of the projectile according to the invention on the game body causes rupture of the shell and a leakage of the fluid and the packing. Due to the impact and the associated negative acceleration of the fluid whose viscosity is greatly increased and the fluid splinters. The fragmented fluid and the packing lead to mechanical damage to the surrounding tissue and promotes the favorable for the fast shooting effect nerve shock. Meanwhile, the bullet almond travels with the formation of projectile shell flags, which also causes a high energy output and mechanical injuries, coupled with shock effects. Due to the strong cross-sectional enlargement of the projectile shell is slowed down and usually does not hit the game body. As a result, significantly improved safety is achieved in the environment and in the hinterland of the destination with simultaneous high energy output to the destination.

The splinters of the fluid and the packing are slowed down in the tissue quickly. As the velocity of the chips of the fluid decreases, so does the shear rates produced in the chips, and the viscosity decreases. From the splinters are again drops of the fluid, which poses no danger. Especially when other people or dogs are present at the firing, the greatly reduced risk of bullet remains at the same time maximum energy output in the target is extremely low.

Also for use on shooting ranges or in the shooting cinema, the projectile according to the invention is suitable because the projectile energy in the target, z. B. is easily dissipated at the ball catch and no high penetration capacity of the projectile is given.

In a further embodiment of the projectile according to the invention, at least one circumferentially extending guide band for guiding the projectile in a tube through which the projectile can be fired is present on the projectile central part. The tube is preferably the barrel of a firearm.

By means of such a design, by means of the at least one guide band, a gas seal can be achieved during the development of the shot while the friction of the projectile is reduced. Thus, higher speeds of the projectile can be achieved with the same gas pressure, whereby the lower weight of the projectile according to the invention compared to a metallic or ceramic basement can be compensated. For example, a projectile with a projectile weight of 8 g accelerated to 800 m / s has an energy of around 2560 J. The strong acceleration during firing increases the viscosity of the fluid considerably. As a result, a compact bullet core is formed, the no has adverse effects on the precision of the projectile according to the invention.

It is also advantageous if the projectile casing, in particular in the region of the projectile head, is designed such that an easy and controlled tearing of the projectile casing upon impact is achieved. For example, the projectile casing in the region of the projectile head can have a depression comparable to an open hollow point. In a further embodiment, a cavity is present under the projectile jacket in the region of the projectile head.

In addition, the projectile jacket may have structures by which a entrainment of the fluid and the filler body is supported in a rotation of the projectile about its longitudinal axis. Such structures may be, for example, projections, shoulders or increased surface roughnesses of the shell jacket.

The projectile according to the invention can be used in ammunition, in particular for shooting sports and hunting.

One embodiment relates to the use in cartridges for practice shooting, for example, in the shooting cinema. Advantageously, the bullet is also suitable in cartridges for hunting, in particular for the shooting or shooting in densely populated areas.

According to the invention, a fluid having non-Newtonian properties, having an increasing viscosity due to shear forces caused in the fluid, and fillers embedded in the fluid are used as target ballistically effective mass in a projectile.

The object is further achieved by a method for producing a projectile having a projectile jacket and a projectile core at least partially surrounded by the projectile jacket, wherein the projectile core contains at least one fluid with non-Newtonian properties, the viscosity of which increases as a result of shear forces in the at least one fluid and in the fluid packing are introduced.

The invention will be explained in more detail with reference to embodiments and figures. Show

6 a sixth embodiment of a projectile according to the invention in longitudinal section.

A first, shown in partial section, embodiment of a projectile according to the invention 1 is according to 1 spherical design, has a bullet jacket 2 and has a line of weakness along one of its perimeters 4 in the form of a furrow along which a wall thickness of the bullet jacket 2 is less than a wall thickness of the remaining shell of the shell 2 , A bullet core is through a fluid 3 formed with non-Newtonian properties. In the fluid 3 are spherical fillers 13 (only some examples and shown schematically) embedded in steel. The first version of the projectile 1 is intended for use as lead-free ammunition with reduced punch-through effect for muzzle-loading weapons. In other versions, more than one line of weakness may be present 4 to be available.

A second version of the projectile 1 for use in rifle barrels with classical fields and trains or in runs without fields and trains, for example in polygons, is in 2 shown. The projectile 1 has a longitudinal axis 1.1 on and has an ogival bullet head 1.2 , a floor centerpiece 1.3 and a bullet tail 1.4 , In the direction of the longitudinal axis 1.1 run on opposite sides of the bullet jacket 2 and 180 ° to each other about the longitudinal axis 1.1 offset two lines of weakness 4 that go along the bullet head 1.2 and the floor centerpiece 1.3 available. The bullet core is through the fluid 3 (Polydimethylsiloxane and borate) and star shaped packing 13 (only some examples and shown schematically) made of ceramic filled.

This design is particularly suitable for use on shooting ranges with short shooting distances of about 15 to 50 meters, for example in 3D shooting ranges and in shooting cinemas. Very favorable is the lead-free structure of the projectile 1 , a problem-free disposal of bullet scraps and a significantly reduced burden on the bullet trap.

A third embodiment of the projectile according to the invention 1 is in 3 shown as a longitudinal section and similar to that of the second embodiment (see 2 ). There are four to each other by 90 degrees about the longitudinal axis 1.1 staggered lines of weakness 4 (only two of which are shown as hidden body edges). The bullet jacket 2 has at its the bullet core side facing two (one shows) in the direction of the projectile core protruding projections 8th in the form of slats. The one by the fluid 3 and spherical fillers 13 (Only some examples and schematically shown) formed of lead bullet surrounds the projections 8th on all her free pages. During a rotation of the projectile 1 around the longitudinal axis 1.1 How this is done in a swirl stabilization of rifle bullets, the fluid 3 accelerated on launch and its viscosity increases. During the flight of the projectile 1 its speed decreases slowly. Also the viscosity of the fluid 3 sinks again. When hitting a target (or obstacle) becomes the projectile 1 slowed down greatly, causing the viscosity of the fluid 3 rises again. During all these phases there is entrainment of the fluid 3 and the filler 13 through the projections 8th causes. This is a ballistic behavior of the projectile according to the invention 1 comparable to a compact bullet made of solid materials.

In other embodiments, more, for example, three, four, five or six projections 8th be arranged. These can also be shaped and arranged differently. So the projections can 8th each also be multi-part, each other in the direction of the longitudinal axis 1.1 arranged offset and / or be designed differently than a lamellar.

In the area of the floor middle section 1.3 and the storey back 1.4 are on the floor 1 two guide bands 7 existing. The projectile 1 is slightly sub-caliber, ie its diameter outside the guide bands 7 is less than a nominal diameter of a barrel with fields and trains through which the bullet 1 to shoot. The guide bands 7 have such a large diameter that they are pressed when shooting in the trains of the barrel and a gas seal against the propellant gases is reached.

In a fourth embodiment of the projectile 1 the bullet jacket, as in 4 shown schematically, in the area of the storey tail 1.4 a connection area 6 on. The bullet tail 1.4 is entirely from the connection area 6 filled in by an area of the bullet jacket 2 is formed, the wall thickness greater than the wall thicknesses of projectile head 1.2 and floor centerpiece 1.3 is.

Tear the bullet jacket 2 along the lines of weakness 4 on, arise depending on the number of weakening lines 4 a number of laterally through each one line of weakness 4 limited bullet coat banners 5 that penetrates into a target from the longitudinal axis 1.1 be bent radially outward. The lines of weakness 4 end with the middle section of the floor 1.3 , The radially outwardly curved bullet flags 5 remain at the connection area 6 , creating a high cross section of the projectile 1 is effected in the goal. In addition, due to the increased cross-section, the penetration capacity decreases, as a result of which a high energy output is achieved and, at the same time, a risk due to isolated parts of the shell shell 2 is reduced.

A rupture of the lines of weakness 4 is due to the design of the bullet head 1.2 supported. This is about the longitudinal axis 1.1 rotationally symmetrical as a dome-shaped depression 9 designed. The lines of weakness 4 reach to the depression 9 approach.

At a hitting the bullet 1 The bullet jacket becomes an obstacle 2 in the area of the bullet head 1.2 loaded in the radial direction (shown by an arrow for example). By this directed force effect is the tearing of the bullet jacket 2 along the lines of weakness 4 starting at the bullet head 1.2 supported.

A fifth embodiment of the projectile according to the invention 1 also has one connecting area 6 on. In this embodiment, has the bullet head 1.2 an externally closed surface. Below the surface is one around the longitudinal axis 1.1 rotationally symmetric cavity 10 available. At a hitting the bullet 1 with a minimum impact energy to a target, the bullet jacket becomes 2 in the area of its tip in the cavity 10 pushed. During penetration or continued impact on the target, the bullet jacket becomes 2 in the area of the bullet head 1.2 loaded in the radial direction. By this directed force effect is the tearing of the bullet jacket 2 along the lines of weakness 4 starting at the bullet head 1.2 supported.

The sixth version of a projectile 1 , shown in 6 , is suitable for firing from smooth barrels (eg from shotgun barrels). The one by the fluid 3 and spherical fillers 13 Bullet core formed from a zinc-tin alloy is of the bullet jacket 2 laterally and at the rear of the bullet 1.4 surround. The bullet jacket 2 has four lines of weakness 4 on (two shown as a hidden body edge). At the bullet head 1.2 is the bullet core through a domed cap 12 covered. Between the bullet core and the cap 12 is a cavity 10 educated. The projectile 1 owns at its bullet tail 1.4 a stabilizer 11 made of felt or plastic, through which the bullet 1 stabilized during the flight according to the arrow principle.
